I'm trying to use a "Lenovo VDK8736 USB Port replicator with digital video" with Fedora/Gnome 20 64-bit. I'm finding that the USB display adapter is not detected despite the necessary driver (udl) being found and loaded and the corresponding /dev/fb? device being created.

How do I get the new video adapter to be detected with the Gnome desktop?

Supporting information below:

The USB display adapter uses DL165 chipset.

lsusb reports: Bus 003 Device 003: ID 17e9:01e6 DisplayLink

lsmod shows udl driver loaded:

#lsmod | grep udl

udl 24618 1

drm_usb 12990 1 udl

drm_kms_helper 50287 2 udl,i915

drm 283349 8 udl,i915,drm_usb,drm_kms_helper

The udl driver is provided by base kernel package as shown by:

#rpm -qf /usr/lib/modules/3.12.5-302.fc20.x86_64/kernel/drivers/gpu/drm/udl/udl.ko


Two frame buffer devices present:

#ls -ld /dev/fb*

crw-rw----. 1 root video 29, 0 Jan 13 11:09 /dev/fb0

crw-rw----. 1 root video 29, 2 Jan 13 13:49 /dev/fb2

fb2 corresponds to the udl driver.

Make sure you use, though. I only can get DisplayLink to work on, never Wayland.

Additionally, I installed the driver from the manufacturer using this script to generate the RPM packages (but looks like you have the driver loaded already, but try it just in case dont forget to rebot after installing)
